Red Light Therapy Research Paper

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

Here, a laser of specific wavelength is targeted on a particular area of the skin. The light from the laser beam is absorbed by the flawed outer layer of the skin and results in its vaporization. With the removal of the outer layer, the new, healthier underlying skin develops.

Lasers are highly powerful rays of light and they can harm tissue - however, the lasers used in hair removal are specially designed to pass safely through the skin, targeting the pigmented cells at the root cells of the hairs, underneath the surface, without damaging the surrounding tissue and the skin.

The basic component in tanning is ultraviolet light. Ultraviolet light, whether produced by a tanning unit or by the sun, contains two components; UVA and UVB. These are the two types of ultraviolet radiation that are known to negatively effect the skin. UVA has a longer wavelength that causes photoaging and can produce some melanomas. UVB has a shorter wavelength that also causes photoaging and has been implicated in skin cancers. Photoaging is the premature aging or deep wrinkling of skin. Indoor tanning units utilize both forms of light waves to tan a person with a minimized risk of sunburn. Tanning outdoors does not give you this option because the sun omits every type of UV rays, so a person is more likely to burn. A person’s skin epidermis consists of two layers: The germinative layer and the horny layer. Another name for the germinative layer is the “living layer.” And another name for the horny layer is the “dead” layer. When exposed to ultraviolet light, melanocytes in the germinative layer produce melanin that is absorbed by surrounding cells. Melanin is a dark pigment found in the pigment-bearing cells of the skin, and melanocytes are epidermal cells capable of synthesizing melanin. This creates a protective barrier from ultraviolet light reaching deeper into the layers of the skin. The pale pink melanin granules are stored in the core of keratin cells. UVA darkens the melanin,

Dermatologists, physicists, and scientists conducted a workshop of UVA treatment, and the workshop’s findings are presented in the New England Journal of Medicine. A previous president of the American Academy of Dermatology wrote an article titled “UVA1 is Often A1” to discuss their findings. The workshop found that medium or high-dose UVA1 works well with morphea, urticarial pigmentosa, atopic dermatitis, dyshydrotic dermatitis, subacute pruigo, and systemic lupus erythematosus. These diseases are treated by UVA rays because the wavelength is longer, which means there is less energy delivered to the skin and the greater penetration of photons (Dahl, 2012). Dermatologists even use sunbeds with higher intensity than regular tanning beds in their offices. For example, Windsor Dermatology uses four different types of light therapy to treat the skin condition psoriasis. One type of light therapy is that of UVA. The anti-inflammatory properties of ultraviolet light aid in slowing the growth of psoriasis effected skin

Look for a serum containing 15 to 20 percent l-ascorbic acid, as this is the strength studies have shown produces the most skin benefits with the least amount of irritation. You only need to use it once every morning or evening.

This website has information about all the different surgeries and treatment methods that can be used to remove skin cancer from the body. There’s also information on age spots that can be caused from tanning that contradict with society’s view on tan skin. Some of the surgeries and treatment methods are quite complicated and hard to explain, so I plan on vaguely touching on them and focusing more on the age spot portion.

Several findings are made based on the results: UV radiation can cause cell death by inducing genetic mutation, which agree with Diepegen et al. (2012)’s finding regarding UV radiation’s destructive effect at a cellular level. Photoprotective agents can effectively prevent and reduce UV radiation induced damage to cells. Similar findings were made by Quatrano and Dinulos (2013), who indicated that sunscreen contains active ingredient that absorbs UV radiation ranging between 290-400 nm. This experiment proves that photoprotective agents with higher SPF values are more effective in absorbing UV radiation. Indicated by Green et al. (2011), they suggested that regular application of high SPF sunscreen will prevent melanoma.

Laser resurfacing is another treatment which has taken the cosmetic world by storm in recent years. While it might be more recognisable as a wrinkle eliminator or a tattoo remover, the use of it to treat acne sufferers is remarkable. The laser beams essentially destroy the epidermal layer of the skin, this then allows new skin to generate and fill the pits created from acne

Ultraviolet (UV) radiation is present in normal sunlight and sunlamps. “The sun emits energy over a broad spectrum of wavelengths: visible light that [one] can see, infrared radiation that [one] feels as heat, and ultraviolet (UV) radiation that [one] cannot see or feel. UV radiation has a shorter wavelength and higher energy than visible light. It affects human health both positively and negatively” (U.S. EPA). There are multiple types of ultraviolet radiation known to scientists and each affects human in different ways. “The longer ultraviolet rays (UVA), which penetrate deep into the skin, are responsible for tanning. Shorter rays (UVB) damage superficial skin cell layers, causing sunburn” (Harvard). Medical researchers at the Skin Cancer Foundation found that “the cumulative damage caused by UV radiation can lead to premature skin aging (wrinkles, lax skin, brown spots, and more), as well as skin cancer” (Skin Cancer Foundation).

ELASTIN is a vital protein that gives skin the capability to "bob once again" in the wake of extending. The breakdown of elastin prompts hanging skin. Sun presentation and rehashed outward appearances harm elastin.

Lasers treatments work by producing heat when interaction with the skin takes place. A quite high beam of light is passed through the skin at the dermal level which makes it quite hot and stimulates the cells which produce elastin& collagen. The laser is also targeted to coloured lesions such as broken blood

Some people think having a tan gives them a "healthy glow." But a tan really shows that the skin is trying to protect itself from sun damage. Sun damage can lead to premature aging (wrinkles!), eye damage, and skin cancer.When a type of radiation (ultraviolet [UV] radiation) is exposed to the skin, the skin responds by producing melanin. Melanin is a dark substance that helps prevent the body from taking in too many harmful sun-rays that can damage skin.The sun produces two kinds of rays, UVA and UVB. UVB rays are around all year and UVA rays are mostly present only during the summer. UVA rays are regarded as "safer" and they cause the skin to age, while UVB rays cause the skin to burn. However, both of these types of rays are harmful and

In intense pulsed light (IPL) therapy, a hand laser is allowed to pass over the skin that targets the melanin. This form of melasma laser treatment works best on the epidermal melasma type. The light energy heats up the melanin cells and destroys them. Before going for IPL treatment for melasma, consult your doctor regarding your type of melasma and also determine whether IPL treatment is suitable for you.

Every hour at least one American will die of skin cancer caused by exposure to the sun. These statistics are alarming and most people are unaware that the sunshine that we all love so much is in fact a threat to our health and good looks. It is up to us to educate ourselves and our children on the harmful effects of sun exposure on the human body like premature aging, physical damage to the body, and cancerous diseases.
